Failed migration

Hi, everybody.

Last week I made a WP migration from a server to other, and it worked perfectly. So, right now, I needed to move the WP from a folder to other (from /site to root), and made the same process.

Now /site is unavailable, the import is not working (something with some array on the line 1040 of some site origin php…), and the root is a mess.

It seems the users are there, and also the posts and pages. But no media is being recognized, even they are at the uploads folder. And all the site information, and CSS, and everything else, reseted.

Is there a easy way to put everything all right again? What I can do with the xml file, I mean, is this still useful?

Thanks.
